Definitions

  • the present specification refers to a patent application for an innovative concept in the adhesion between layers of a ballistic composite exactly at the points of impact and deformation region and in the closing of the pores in raw fabrics, where at least two layers of fabric are impregnated with a polymeric resin and, between them (upper fabric layer and lower fabric layer), an elastomeric polymer is inserted.
  • This arrangement is then hot-compacted at a specific temperature, causing, through the fluidity offered by the polymeric resin, the passage and uniform filling of the pores of the two layers of fabric by the elastomeric polymer, forming a ballistic tissue group.
  • the impregnation of the polymeric resin when applied to unidirectional non-woven fabrics that do not have pores, the impregnation of the polymeric resin must occur on the opposite side to the side that will receive the elastomeric polymer.
  • Each group is assembled in several units to form a ballistic shield, used in ballistic protection systems such as ballistic vests and in armor in general.
  • This composition has multiple blades, used to control laminar drawing. [010] In any case, for the best efficiency in the control of the longitudinal drawing of the ballistic fibers and impact absorption, it is necessary an adequate interaction between the layers that make up the shield, to obtain the necessary security.
  • the layer grouping system for absorbing ballistic impacts which is the reason for this patent application, comes to propose exactly the reduction of the ballistic fibers (elongation) used in bulletproof vests during the impact of the projectile, obtaining them a significant reduction in trauma (BFS) measured on a control mass (supporting material) in line with current ballistic testing standards.
  • BFS trauma
  • the fabric also makes possible a greater area of ballistic protection in vests and optimization of the use of ballistic fiber, obtaining less weight, impermeability and giving greater flexibility in the whole group formed, in addition to acquiring greater resistance to threats by sharp objects .

Abstract

L'invention vise à dissiper uniformément l'énergie d'impacts balistiques dans les fibres des couches de blindage balistique, au moyen d'un assemblage balistique (8). À cet effet, les assemblages balistiques (8) sont obtenus à partir d'au moins deux couches (1) et (2) de tissu balistique, toutes deux revêtues, dans leurs pores (4) et sur leurs faces supérieure et inférieure, d'une résine polymère (3), et entre lesquelles est introduit un polymère élastomère (5), conformément à l'étape de pressage à chaud de l'ensemble. Grâce à un compactage, le revêtement polymère (3) favorise l'écoulement uniforme du polymère élastomère (5) par les pores (4) et les faces des couches de tissu balistique (1) et (2), de manière à former un assemblage balistique (8). Lorsque le blindage est atteint par un projectile (PJ), le revêtement de résine polymère (3) du premier assemblage (8) n'adhère au revêtement de résine polymère (3) de l'assemblage balistique suivant (8) qu'au niveau du point d'impact (IM), et ainsi de suite, particularité qui, associée à la souplesse du polymère élastomère (5), permet une dissipation uniforme de l'énergie des impacts balistiques (IM) sans provoquer de lésions chez l'utilisateur.
